I never owned a Draco, but my first drysuit was the D10.
I enjoyed that suit but I switched to the D7.
Ill start with the cons then on to the pros. I hope this helps
Cons
-Its neoprene, crushed neoprene, but I still had a good amount of buoyancy which meant I needed extra weight. If you've never owned a drysuit before, you'll need a few extra pounds to compensate anyways.
-Its back zipped so you have to rely on someone else to zip you up. I went to Divers institute of technology and I had to have a lot of trust with my tenders and dive buddies in making sure they had me fully zipped. One of the divers who also owned a D10 had the front protected zipper zipped up and not the main one and ended up flooded and cold in Lake Union for an hour. If you don't have a problem with it back zipped, then you'll be fine. Also if you're going to a underwater welding school, I would recommend a back zipper as you can run the risk of burning off a front zipper. Ive seen it happen.
-Its not very flexible especially in the arms, I think due to the neoprene. Its not bad, but it can be annoying compared to other drysuits or wetsuits.
-If you're bony, the neck ring can be a little bit uncomfortable, but it can be fixed with extra padding by placing small towels on your shoulders
-It is possible water will "sweat" through the drysuit. Its not a lot, but I noticed trilams tend to be a little more drier post dive.
Now for the pros:
-Its got an integrated silicone system for the wrist and neck seals. thats the number one thing I liked about this drysuit. Its easy to fix in a pinch and its protected by the neck guard. The seals can be pricy, but if you're careful with your seals, Its worth it. Not to mention you're saving time lost sending it out to be repaired. They're also a lot more tougher than latex, providing an excellent seal.
-Its heavy duty, so it can take a beating. Like this thing is built like a tank. I spent almost a year under lake union with that drysuit and there was little sign of excessive wear compared to my classmates who sported the northern diver.
-You won't need as much undergarments to wear compared to a trilam drysuit as the neoprene is much thicker, creating more insulation
-If you're familiar with working with wetsuits and fixing them, its almost the exact same concept.
-The drysuit comes with two pockets. Need I say more on them? More room for sunken treasure!
-The suit squeeze isn't as bad compared to a trilam
Overall, if I had to go back to a neoprene drysuit, Id go back to the D10. When writing this, I noticed I was comparing it more to a trilam. Sorry about that.
I did look up a draco drysuit however and the only difference I saw with it was that the draco doesn't have the integrated silicone system. Im assuming its also a little more cheaper if you can find it. The links I clicked on showed they were no longer available.
The link provided will give you an idea what its like to don a waterproof drysuit with a back zipper.
Hope this all helps
